The council rationalised the 28 per cent slab by bringing down the tax rate on seven items in the highest tax bracket, thereby leaving only 28 items in the slab.

Briefing reporters after the 31st GST Council meeting here, Jaitley said rate rationalisation is an ongoing process.

"28 per cent bracket is gradually moving to sunset... The next target will be rate rationalisation in cement as and when affordability improves," he said.

Now, the 28 per cent slab is restricted to only luxury and sin goods, apart from auto parts and cement - tax rates on which could not be cut due to the high revenue implication.

GST on movie tickets costing up to Rs 100 was cut to 12 per cent from 18 per cent, while tickets over Rs 100 will attract 18 per cent tax, against 28 per cent earlier. This will have a revenue implication of Rs 900 crore.

Monitors and TV screens up to 32-inches and power banks will attract 18 per cent GST, as against 28 per cent earlier.
